摘　　要：针对机翼振动响应较大问题,通过仿真模拟预测和机上地面试验验证相结合的方式,研究并验证LMS控制律方法在真实机翼上实现振动主动控制技术的可行性。仿真模拟中,采用Patran进行结构建模和压电力等效,通过matlab的Simulink模块搭建控制仿真模型;机上地面试验中,设计了以压电纤维复合材料作为控制器,激振台作为激振器的地面试验方案。结果表明,通过优化参数,LMS控制律方法在仿真模拟和地面试验中均较好地抑制了振动响应,从而在机翼上实现主动控制技术。In order to reduce the large amplitude response of the wing-vibration, the LMS control method has been used to validate the feasibility of the active vibrate to the true wing, which made use of simulate experiment for forecast and the ground test for validation. In the simulation study, the experimental model is made up of two components, one is the Patran which builds the FEM of the wing and plays the role of the Piezoelectric force, and the other is the Simulink tool of Matlab software. In the ground test study, a new experimental scheme is designed, which uses the vibration exciter as the exciting device, the Macro Fiber Composites （MFC） as the control device; The results show that the LMS control method, by tuning optimized parameters, has successfully suppressed the amplitude response of the wing-vibration in both simulation and ground test studies, which reveals that LMS control method has the potential to implement the active control technology of the true wing.
